The sum of organic nitrogen and ammonia in a water body.
Measured in milligrams per liter (mg/L). High measurements of
TKN typically results from sewage and manure
discharges to water bodies.

State Superfund sites, also referred to as or Permanent List of
Priorities (PLP) sites, are those the state intends to
investigate and cleanup under the Minnesota Superfund Program.
Known or suspected environmental contamination threatens public
health, welfare or the environment at PLP sites. These sites
include those addressed by the MPCA, as well as sites with
agricultural chemical contamination which are addressed by the
Minnesota Department of Agriculture. For more information,

State Closed Landfill Program sites are closed municipal waste
landfills that were formerly permitted by the state. After a
binding agreement is negotiated between the MPCA and the site
owner/operator, the state takes responsibility for monitoring
and cleanup systems needed for long-term care.

Indicates the degree to which light is scattered in water by
suspended particulate material and soluble colored compounds.
It provides an estimate of the muddiness or cloudiness of the
water due to clay, silt, finely divided organic and inorganic
matter, soluble colored organic compounds, plankton, and
microscopic organisms. Measured in Nephelometric Turbidity
Units (NTU) or Formazin Turbidity Units (FTU).

the file that contains the image taken of your stream site at
the time of sampling.

Write "Picture" in the "Comments" space each time a picture is
taken. Use this space to record anything unusual that you
observe during a sampling visit; note things like recent severe
weather, construction activities occurring upstream, changes in
adjacent land use, etc.

Each day that you sample, please record the one number that
best describes the appearance of stream water within one meter
of your sampling site.<br><br>

Please use the one number each day that you sample that best
describes your opinion of how suitable the stream water is for
recreation and enjoyment.

If a pre-established gage is installed at your site, enter the
surface water level in feet and decimal feet (e.g. 2.15) taken
from the gage at the time of sampling.

Enter the stream water temperature in degrees Fahrenheit, to
the nearest degree.
